Our laboratory is located in recently renovated space in Peterson Hall. The building underwent a complete renovation, with all new utilities, in the summer of 2012. You'll find us on the third floor in rooms 310 (instrument room), 311 (laboratory), 323 (laboratory), and 324 (office).
Field instrumentation
For measurements made on site, we have
- YSI 556 and YSI ProPlus Multi-Parameter Systems (measures dissolved oxygen, temperature, conductivity, and pH) with a 10 m cable and flow through cell
- Multiple YSI Dissolved Oxygen meters
- Hach 2100Q and 2100P turbidimeters
- Turner field fluorometers for in vivo measurement of chlorophyll
- Thermo Niton XL3t handheld XRF analyzer for measuring metals in solids (such as soil)
- Van Dorn samplers
- Sontek FlowTracker2 Acoustic Doppler Velocimeter (for wadable stream flow measurements)
- Teledyne RDI Stream Pro - Acoustic Doppler Profile Velocimeter (for higher flows)
- Hach NitraTax in situ nitrate monitors
- ISCO samplers
Laboratory instrumentation
When we bring the samples back to the lab, we use
We also have the following instrumentation and equipment available for special projects.
Support for these instruments has been provided by the National Science Foundation, the Department of Energy, the Pittsburgh Conference National Memorial College Grant, the city of Cedar Rapids Utility Department, Greater Cedar Rapids Community Foundation, and by Coe College.
- Metrohm IC with 840 Professional Sample Processor - this is our mainstay for analysis of nitrate, chloride, and sulfate
- Lachat QuikChem 8500 Series 2 Flow Injection analyzer - measures dissolved reactive phosphorus (DRP, orthophosphate) down to the part-per-billion level as well as total phosphorus (after digestion with an Environmental Express Hot Block)
- IDEXX Colilert 18/Quanti-tray system for measuring E. coli in water.
- Buck Scientific cold vapor mercury analyzer capable of detection limits of 10 parts per trillion (!) in aqueous solutions
- TitraLab AT1000 Series Potentiometric Titrator for hardness and alkalinity
- And of course pH meters, ovens, analytical balances, furnaces, etc.
We also have the following instrumentation and equipment available for special projects.
